Compilation error with gcc version 9.3.0 (Buildroot 2020.08-14-ge5a2a90)

While cross compiling with gcc version 9.3.0 (Buildroot 2020.08-14-ge5a2a90) 

I hit with this compilation error:

WebCore/DerivedSources/JSRTCRtpSender.cpp: In function ‘JSC::JSValue WebCore::toJSNewlyCreated(JSC::JSGlobalObject*, WebCore::JSDOMGlobalObject*, WTF::Ref<WebCore::RTCRtpSender>&&)’:

Oh, that's because your port doesn't subclass LoggerHelper.

Thanks! Let me look at it :)

But still, LoggerHelper inheritance is conditional...
